The camera came to life after almost 2 hours waiting.
During the hour and a half that I was working with it, I was taking mostly pictures, but yes, I took by error a 1 min 8x slow motion video, but as you said, it shouldn't do that.
I'm new on Fuji, I moved from my old Nikon D800 to the mirrrorless planet, and I'm super impressed with this tiny camera, but this issue got to said that was a boomer.
